Definitions

  • the known method not only requires a complex construction, but is also complicated in terms of control technology and requires a large number to achieve control equipment. Accordingly, it requires a considerable amount Investment. Furthermore, it brings with it a large degree of production uri security, because of the large number of continuously intervening drive units in the event of failure part of the whole process is stopped and the casting process is stopped must become.
  • the first Deformation step must always be carried out, otherwise one necessary for winding Thinness of the product and therefore production cannot be guaranteed. So that is the known method for certain steel grades not feasible. Furthermore is targeted and flexible temperature control with regard to the quality of the finished product hardly possible, especially in transient conditions. If the winding unit fails the overall process also comes to a standstill immediately; this also includes the standstill of the Pouring process.
  • a method for producing a tape in a thickness of 2 to 25 mm is known from the EP-B 0 286 862 known.
  • a steel strand is cast formed by melt in a funnel-shaped continuous mold and while passing through the same already deformed.
  • the strand which still has a liquid core, becomes after Exit from the continuous mold so compressed that there is a weld of inner walls of the already solidified strand shells comes. This will create a Thickness reduction to a thickness of less than 25 mm achieved.
  • This known method leaves however, only apply to very specific steel grades, namely those that have a allow such deformation just below the continuous mold.
  • the funnel-shaped continuous mold does not allow an even flow distribution, i.e. it can by the pouring jet emerging from the dip tube already strong stressed strand shell at the critical deformation points by melting weakened, which manifests itself in increased risk of breakthrough.
  • Another disadvantage lies in the very low flexibility in terms of production capacity and in terms of the utilization of the full casting speed range.

  • the deformation in the first Deformation stage in a manner known per se immediately after the strand emerges from the Mold is carried out, advantageously the deformation in the first deformation stage in is known to be carried out in a plurality of substeps.
  • Descaling is expediently the second deformation stage in a manner known per se upstream.
  • the high flexibility of the method according to the invention enables that, preferably by the first two stages of the process, applied individually or together, reduce the Thickness of the strand down to a minimum thickness of 30 mm is carried out. Consequently the severed strand has a thickness of at least 30 mm before it Further rolling is fed.

  • the strand 4 descaling in a descaling device 11 subjected to soft descaling by means of rotating Descaling nozzles and with special water wipers for the descaling water enables.
  • the thickness pre-reduction allows one before the temperature compensation Influencing the end product quality especially for microalloyed steels, which are usually replaced by appropriate Stitch decreases above the recrystallization stop temperature Precipitation and recrystallization processes are influenced.
